Diabetes eye screening in urban settings serving minority populations: detection of diabetic retinopathy and other ocular findings using telemedicine.

IMPORTANCE: The use of a nonmydriatic camera for retinal imaging combined with the remote evaluation of images at a telemedicine reading center has been advanced as a strategy for diabetic retinopathy (DR) screening, particularly among patients with diabetes mellitus from ethnic/racial minority populations with low utilization of eye care. OBJECTIVE: To examine the rate and types of DR identified through a telemedicine screening program using a nonmydriatic camera, as well as the rate of other ocular findings. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional study (Innovative Network for Sight [INSIGHT]) was conducted at 4 urban clinic or pharmacy settings in the United States serving predominantly ethnic/racial minority and uninsured persons with diabetes. Participants included persons aged 18 years or older who had type 1 or 2 diabetes mellitus and presented to the community-based settings. MAIN OUTCOMES AND MEASURES: The percentage of DR detection, including type of DR, and the percentage of detection of other ocular findings. RESULTS: A total of 1894 persons participated in the INSIGHT screening program across sites, with 21.7% having DR in at least 1 eye. The most common type of DR was background DR, which was present in 94.1% of all participants with DR. Almost half (44.2%) of the sample screened had ocular findings other than DR; 30.7% of the other ocular findings were cataract. CONCLUSIONS AND RELEVANCE: In a DR telemedicine screening program in urban clinic or pharmacy settings in the United States serving predominantly ethnic/racial minority populations, DR was identified on screening in approximately 1 in 5 persons with diabetes. The vast majority of DR was background, indicating high public health potential for intervention in the earliest phases of DR when treatment can prevent vision loss. Other ocular conditions were detected at a high rate, a collateral benefit of DR screening programs that may be underappreciated

Is the physical functioning of older adults with diabetes associated with the processes and outcomes of care? Evidence from Translating Research Into Action for Diabetes (TRIAD)

Aims  To examine the relationship between physical function limitations and diabetes self‐management, processes of care and intermediate outcomes in adults ≥ 65 years of age with Type 2 diabetes. Methods  We studied 1796 participants 65 years of age and older in managed care health plans enrolled in Translating Research into Action for Diabetes (TRIAD). Physical functioning was assessed at baseline with the Physical Component Summary of the Short Form‐12 Health Survey. Diabetes self‐management was assessed with follow‐up surveys, and processes of care (eye examinations, urine microalbumin testing, foot examinations, etc.) and intermediate health outcomes (HbA 1c , blood pressure, LDL cholesterol) were assessed with medical chart reviews. Multivariate regression models were constructed to examine the associations between physical function limitations and outcomes. Results  Frequency of eye examinations (odds ratio 0.69, 95% CI 0.49–0.99) was the only process of care that was worse for participants with physical function limitations ( n  = 573) compared with those without limitations ( n  = 618). Neither self‐management nor intermediate outcomes differed by whether patients had or did not have physical function limitations. Conclusion  Limitations in physical functioning as assessed by the Short Form‐12 were not associated with substantial difference in diabetes care in adults ≥ 65 years of age enrolled in managed care health plans.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/93563/1/j.1464-5491.2012.03584.x.pd

OBJECTIVE—To assess changes in the quality of care in Norway for patients with type 2 diabetes

Impact of Pay for Performance on Ethnic Disparities in Intermediate Outcomes for Diabetes: A Longitudinal Study

OBJECTIVE—The purpose of this study was to examine the impact of a major pay for performance incentive on trends in the quality of diabetes care in white, black, and South Asian ethnic groups in an urban setting in the U.K

Patient Race/Ethnicity and Patient-Physician Race/Ethnicity Concordance in the Management of Cardiovascular Disease Risk Factors for Patients With Diabetes

OBJECTIVE Patient-physician race/ethnicity concordance can improve care for minority patients. However, its effect on cardiovascular disease (CVD) care and prevention is unknown. We examined associations of patient race/ethnicity and patient-physician race/ethnicity concordance on CVD risk factor levels and appropriate modification of treatment in response to high risk factor values (treatment intensification) in a large cohort of diabetic patients. RESEARCH DESIGN AND METHODS The study population included 108,555 adult diabetic patients in Kaiser Permanente Northern California in 2005. Probit models assessed the effect of patient race/ethnicity on risk factor control and treatment intensification after adjusting for patient and physician-level characteristics. RESULTS African American patients were less likely than whites to have A1C <8.0% (64 vs. 69%, P < 0.0001), LDL cholesterol <100 mg/dl (40 vs. 47%, P < 0.0001), and systolic blood pressure (SBP) <140 mmHg (70 vs. 78%, P < 0.0001). Hispanic patients were less likely than whites to have A1C <8% (62 vs. 69%, P < 0.0001). African American patients were less likely than whites to have A1C treatment intensification (73 vs. 77%, P < 0.0001; odds ratio [OR] 0.8 [95% CI 0.7-0.9]) but more likely to receive treatment intensification for SBP (78 vs. 71%, P < 0.0001; 1.5 [1.3-1.7]). Hispanic patients were more likely to have LDL cholesterol treatment intensification (47 vs. 45%, P < 0.05; 1.1 [1.0-1.2]). Patient-physician race/ethnicity concordance was not significantly associated with risk factor control or treatment intensification. CONCLUSIONS Patient race/ethnicity is associated with risk factor control and treatment intensification, but patient-physician race/ethnicity concordance was not. Further research should investigate other potential drivers of disparities in CVD care
